The Intersil X90100 is a non-volatile electronically programmable capacitor with a stable dielectric and low temperature drift coefficient.
The X90100 is a non‑volatile electronically programmable capacitor that retains its setting via internal EEPROM after power is removed. It is programmed through three digital pins (INC, U/D, CS) with a simple up/down interface, providing 32 capacitance steps in 0.23 pF increments.
The device operates from a 5 V supply, supports a temperature range of –40 °C to +85 °C, and offers 100‑year data retention with a minimum endurance of 100 000 data changes per bit. Its MSOP‑8 package makes it suitable for RF tuning, low‑drift oscillators, and capacitive sensor trimming.
